Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730738, here are decompositions:

41 + 8730697 = 8730738
47 + 8730691 = 8730738
89 + 8730649 = 8730738
109 + 8730629 = 8730738
127 + 8730611 = 8730738
131 + 8730607 = 8730738
179 + 8730559 = 8730738
227 + 8730511 = 8730738

Showing the first eight; more decompositions exist.
